Ive found in some situations champions perform better & last longer than NGK's.

I have a NGK from hell, little **** wont foul! This thing had bad crank seals, it eats its trans fluid in 20 minutes, but the plug has been working fine. Just luck, first one quit in 5 minutes.

I like the E3s, I had a 3 horse Briggs that would take 5+ pulls to start and would idle erratically and I changed the plug to an E3 and it would start on the second pull and idle fine.

I hate those E3 plug's. Every experience I have had with them is crap!

Plugs go bad over time, if you put another champ or NGK in there it would have fixed it.

nope tried multiple plugs and the E3 was the only one that fixed it

Then there is something else going on.
Saying engine will only run properly on one specific type or brand of plug just makes no sense.
I suspect wrong heat range or faulty ignition. E-3 is providing a patch or bandaid for some underlying/undiscovered problem.

used a E3 plug on an 8hp Techumseh (4-stroke L-head) for a snow blower.
it was to replace Champion #J8C. it fouled up way to quickly (not even an hour of running). it didnt match the Champion plug properly (as it said it did - the E3 was a cold plug, Champ.#J8C is a hot plug).
replaced that with an Autolite plug and havent had any problems.

also got an E3 to replace Champ.#CJ8 (the cold version of J8C) on a 3.5hp Briggs L-head for a mower, but i put it on last fall when i rebuilt the engine. havent run it enough to know how it performs in that application yet. (the E3 in this case is a cold plug also, so i dont think i will have the same problem. but I'll find out when mowing season comes around)
